Google announced the launch of Knowledge Graph, an enhancement to Google Search. Google will analyze your query and display information that are relevant to what you searched for. Google claims that its database contains more than 500 million objects and more than 3.5 billion facts about and relationships between these different objects. This function is currently available to Google.com US English users only, it will also be available to smartphones and tablets later.

So what does Google Knowledge Graph offer? For example, if you search for “Taj Mahal”, Google brings out both information about the monument and the musician. No matter what you are searching for you don’t miss relevant info.

Besides, you get a summary of the entity you are searching for. Without having to go into the result pages, you get an overview of information.

Google will even go deeper to explore the relationship of the search query with other objects. For example, if you search for somebody’s name, his parent’s and sibling’s names would appear.

The knowledge graph occupies the right hand side of the results page so it does not affect the original search results. My first impression is that Google puts up a mini encyclopedia right on the results page. It is most useful when you search for hard facts about a place, a celebrity, an object, etc. because you’ll no longer need to click the Wikipedia page on the results page.
